Carburetor or Fuel Pump Issue

Alternatively, I've heard that some have used an el-cheapo method by utilizing two washers instead of the correct single, but as this seal is critical to the operation of the valve, I cannot recommend this method.

What do you recommend? A new carburetor? Who rebuilds these carburetors? I think I might get a whole rebuild kit and give that a shot.
